Empirical Research Methodologies in Second and Foreign Language
Studies
 CREAL - University of Ottawa
 May 2, 1997

As part of a symposium on empirical research methodologies in second
and foreign language studies (May 2-3, 1997, University of Ottawa),
the Centre for Research on Language Teaching and Learning (CREAL) of
the University of Ottawa would like to include a poster session.

This poster session will offer researchers and student-researchersthe
opportunity to share their research whether it be individualprojects
or master's or doctoral studies. Research selected for the poster
session will provide illustrative examples of the features of the
methodology chosen. About fifteen posters will be displayed during
the symposium. These will be introduced briefly (3-4 min.) by their
authors. If you would like to take part in the poster session, please
submit two resumes as follows: a 500 word resume describing your study
in either English or French which will be used to evaluate your
submission and will appear in the proceedings, and a shorter 150 words
resume in either language which will appear in the symposium program
if your submission is selected.

You are asked to submit your resumes by electronic mail if
possible.These should be sent as a message rather than as an
attachment and should be preceded by your complete address. Please
send your submissions to: drenieuottawa.ca . If you are unable to
send your resumes by electronic mail, please send them on diskette
(Mac or PC), ensuring their arrival before the date given below.

The final date for receipt of proposals is Friday, February 28, 1997.
Notifications of acceptance will be sent during the week of March 15,
1997.

Speakers invited to the symposium:
Alain Desrochers (U of O)
Lise Duquette (U of O)
Claude Germain (UQAM)
Birgit Harley (OISE)
Denise Lussier (McGill)
Mary McGuire (McGill)

 SECOND CALL FOR PAPERS AND PARTICIPATION
 for the Workshop on

 COMPUTATIONAL ENVIRONMENTS FOR GRAMMAR DEVELOPMENT
 AND LINGUISTIC ENGINEERING

 July 11 or 12, 1997


 in conjunction with the 35th Annual Meeting
 of the Association for Computational Linguistics
 (ACL'97/EACL'97 Joint Conference)
 July 7-11, 1997
 Madrid, Spain


WORKSHOP DESCRIPTION


With a growing number of NLP applications going beyond the status of
simple research systems, there is also a more evident need for better
methods, tools and environments to support the development and reuse
of large scale linguistic resources and efficient processors. This
new area of research, often referred to as Linguistic Engineering, is
rapidly gaining interest along side the more traditional ones
concerned with formalisms or algorithm studies and development.

Aspects of linguistic engineering range from grammar development
environments, through the construction and maintenance of large scale
linguistic resources, to methodologies for quality assurance and
evaluation. Some of the most prominent examples of sophisticated
development platforms comprising tracer, debugger and all kinds of
highly important visualization tools are ALEP (funded by the European
Union), GATE (common infrastructure for building LE architectures
using pre-existing components), GWB (LFG-workbench developed at Xerox
Parc) PAGE (typed feature logics-based grammar development developed
at DFKI), and many others. There have been a number of projects on
the development of large-scale computational lexicons (e.g.
Acquilex), as well as projects concerned with the development of
standards and reference data for diagnostics and evaluation
(e.g. TSNLP).

However, while these platforms and components typically provide fairly
clean formalisms, processing components and data, it is not yet clear
to which extent current results and approaches fit the requirements
for scale development and deployment of real NLP applications.

In this connection, a number of pending issues need be addressed, the
relevance of which becomes particularly clear when the focus is
shifted from linguistic formalism to usability and user/application
requirements. The following points are examples of relevant topics:


- What is the state of the art in Grammar Development Environments?

There are a number of systems on the market already. Given the
enormous cost of developing such environments, it is unlikely that
many others will be developed from scratch. Up to what point do the
existing systems meet actual user requirements? What experiences are
there in tailoring such systems to specific applications?


- How can we meet the demands arising from distributed grammar
development?

Even if in the past the biggest systems have been based on the work of
one individual, it is unwise and unpractical to have one large grammar
developed by single writers. Thus, the development and maintenance of
large grammars tends to be more and more a joint effort involving many
computational linguists. What specific requirements and prerequisites
have to be met in a development environment to ensure a smooth
cooperation between different authors leading to the necessary
modularity, consistency and integratability of grammar fragments?


- How can we meet the demands of multi-lingual grammar development?

For many applications (even outside machine translation itself)
multi-linguality is becoming an indispensable standard feature. The
parallel development of several grammars in different languages will
require some synchronization of linguistic knowledge bases and sharing
of processing components. Can different language specific grammars
share a common core grammar? Is it useful to build on modern
formalisms which allow an object oriented design (such as typed
feature logics) or even on theories of a putative "universal grammar".


- What is the appropriate division of labour in a large scale
development environment?

Sophisticated applications may require a whole range of knowledge
sources and processors, addressing, e.g. computational morphology,
syntax, semantics, lexicography, corpus analysis, parsing and
generation to name but a few. What approaches and methods can be
devised and which tools and facilities should be employed to
facilitate and support the integration of different levels of
linguistic abstraction, of different processing modules and the
cooperation between grammar writing and processor design ?


- How can we facilitate the shift from reusability to usability?

Grammar development in academic and research oriented environments has
often concentrated on the maximum generality and reusability of the
linguistic resources developed. However, for building actual
applications and for applying systems to specific domains, this
generality can turn out to be a drawback rather than an asset. Thus,
the question is how one can support the specialization and
customization to more constrained domains without sacrificing the
advantages of more a more general and reusable design.


- What are the necessary ingredients for quality assurance in grammar
development?

The incremental construction of large grammars in particular in a
distributed environment makes it necessary to maintain sufficient
control over different versions. Coverage and speed are expected to
increase over the development cycles. Quality assurance, testing and
diagnostics cannot be carried out properly, if they are based on the
odd collection of test items or some arbitrarily chosen corpus
fragment. Evaluation of a system, which goes even further, will
require a minimum degree of standardization of reference material.
What are then the appropriate methods and data to be applied for these
purposes? How can they be constructed, collected and customized to
specific applications and domains?


The workshop will be the occasion to discuss the results achieved and
the most promising directions and to highlight pending problems.
Contributions are solicited from institutions (both research-oriented
and industrial) involved in the production of NLP applications.

preparation of camera-ready copies of final versions of accepted
papers, conforming to a uniform format, with guidelines and a style
file to be supplied by the organisers.
